Well ive been playing around with different types with basically no luck - In theory this suppressor should work perfectly for a real gun but does not for a paintball gun. What you need is a heavily ported barrel wrapped in a sound absorbing material which of course will ruin your accuracy. This one in the picture is made of pvc with 4 separate baffles filled with cotton and ported. Doesnt deaden sound more than maybe 10%.
Btw ive researched the atf laws on suppressors and it is in fact 100% illegal to build one, mainly because the atf claims that you can remove it and use it on a real gun, so i've taken it apart since it didnt work for paintball anyway.

I love your Gun Spec Ops. its good that you found good customizable parts for your MR1. its hard to find them sometimes i found.

Sorry for the late reply...

Thank you for your kind words.

Yes you're right, aftermarket parts for the Spyder MR series markers ARE hard to find, and especially for the MR1. I barely use this marker anymore though, because I have an MR2 now. I've been trying to sell my MR1 for a while now, but can't seem to find a buyer yet, so in the mean time, I'm thinking about seriously modding it. I thought of putting a G36 airsoft body over it at first, but I'm located in Canada, and airsoft rifle are really hard to get a hold of, so I'm thinking about modding it into a sniper....
I'll post pics whenever I'm done...
